I tube 9 at opposite points.

trance of liquid into the tubes an outer vaporizing siding at Detroit,in the county of Wayne and. tate of Michigan, have invented certain newand useful Improvements in Atom- '1zers, of which the following is aspecification, reference being bad therein to the ac- In atomizers ornebulizers of ordinary type so far as known to me there is no provisionfor preventing entrance of liquid into the spray tubes and moreespecially is this true in instruments of this sort designed for theocket.

-T is invention relatesto an atomizer having special provision forcheckin the eualso for providing a very large volume of spray in proortion to the amount of medicament u as well as to certain featureswhich protect the packing from contacting with the contents.

The invention 'consists in the matters hereinafter set forth and moreparticularly inted out in the appended claims.

In the drawin s, Figure 1 is a view in elevation in exten ed position ofan atomizer embodying features of the invention. Fig.

2 is a view in longitudinal section thereof.

Fig. 3 is a view in cross-section VflfiOl'lZlIig tube.

eferring to the drawings, a cylindrical through a a reservoir 1 has aremovable nozzle 2 of appropriate shape frictionally engaging a lateralapertureinear the base of the reservoi which opens. at about the axialcenter into an outlet tube 3 extending well up toward the top of thepylinder. mouth4 of the outlet tube is outturned laterally andbellshaped. A hollow capo rovided with a tubular flange 6 is screw-treaded into the to of the reservoir 1 and has a lateral rim 7 which actsas a retainer'for a soft packing ring or asket 8. An air tube 9removably secured suitable means in the cap 5 extends well into thebodyof the cylinder. An tube 10 is concentrically secured on this airtube 9 the preferable construction bein 'that indicated wherein theouter tube 10 1s flattened to grip the inner Spray apertures 11 formedin the sides of the two tubes, which are open at the ends, complete thevaporizing means.

' compression cylinder.

agement with the cylinder 1, an 1nner 'annu ar flange 13 at its lowerend acting as a-sto against the shoulder 14 formedon the cy inder 1, anda spiral spring 15, which is tapered so as to close noiselessly, is incompression between the reser V011 cap 5 and a detachable head 16 on theI A packing disk 17' confined by the head 16 against the cylinder endhas a'central tongue or flap 18 acting as a valve against the centralaperture 19 on the head, a hollow boss '20 with air inlets 21 admlttingair to the cylinder through this valve. A lug122 at the lower end of thereservoir is'a apted to pass through a suitable slot in the retainingflange 13 of the compression cylinder 12 so that the latter may be given.a part turn and locked in compressed position for carrying in thepocket.

One quantity of vapor produced when using tie double tubes, inproportion to the small amount of medicament in the reservoir.

Another feature is the shape of the cap for the reservoir which preventscontact of the reservoir contents with the packing.

Another very important detail is the arrangement of the tubes whichprevents escape of liquid through the spray nozzle when the atomizer isbeing carried in the pocket.

Obviously, changes in the details of construction may be made withoutdeparting from the spirit of the invention, and I do not care to limitmyself to any particular form or arrangement of parts.

What I claim as my invention is:-- o 1. An atomizer comprisin acylindrical reservoir permanently close at its lower end, an outlet tubeextending from the lower telescopical en end u ward in. the reservoirand having a latera ly turned bell-mouth upper end, a nozzle extendinglaterally from the lower end of the reservoir that 1s connected by anaperture in the reservoir base with the outlet tube, a hollow capdetachably secured in the upper end of the reservoir, 'a' packipg ringsecured on the cap by an annular run thereon, an air tube 0 eningthrough the cap extending toward t e lower end of the reservoir, anouter vaporizing tube concentrically secured on the. air tube, saidconcentric tubes having alined apertures in their walls, aspring-returned compression An outer compression cylinder 12 has featureof the invention is the lar e y reservoir permanently close cylindertelescoping over the upper end of the reservoir,-an air inlet valve inthe head of the compression cylinder, an annular shoulder on the upperend of the reservoir,

. an inner annular flange on the lower end of the compression cylinderadapted to engage the reservoir shoulder, and a lug on the lower end ofthe reservoir adapted to pass through a slot in said flange,

2; n atomizer comprising a cylindrical reservoir permanently closed atitslower an aperture in the reservoir base with the- 'outlet tube, a caphaving an annular projecting rim at its upper end and a dependingannular flange adapted for screwthreaded engagement with the upper endof the reservoir, a packing ring secured in the cap by the annular rim,an air tube opening through the cap extending toward the lower end ofthe reservoir, an outervaporizing tube concentrically secured on the airtube, said concentric tubes having alined apertures in their'walls, aspringreturned compression cylinder telesco ing over the end of thereservoir, an air inlet valve in the head of the compression cylinder,means limiting the outward movement of the compression cylinder andmeans adapted to lock the two cylinders in compressed position.

3. An atomizer comprisin ar -cylindrical et its lower end, an outlettube extending from the lower end upward in the reservoir and having alaterally turned bell mouth upper end, a nozzle extending laterally fromthe lower endof the reservoir that is connected by an aperture inthereservoir base with the outlet tube, a cap having an annular projectingrim at its upper end and a depending annular fiange adapted forscrewthreaded engagement with the upper end of the reservoir, a packingring secured on the cap bythe annular rim, an air tube opening throughthe cap extending toward erase the lower end ofthe reservoir, an outervaporizing tube concentrically secured on the air tube by meansafi'ording passages between the tubes for the entire length of the outertube, said concentric tubes having alined apertures in their walls, aspring-returned compression cylinder telescoping over the upper end ofthe reservoir, and an inlet valve in the head of the compressioncylinder, means limiting the outward movement of the compressioncylinder and means adapted to lock the two cylinders in compressedposition.

4. An atomizer comprising a cylindrical reservoir permanently closed atits lower end, an outlet tube extending from the lower end upward in thereservoir and having a laterally turned bell-mouth upperend, a nozzleextending laterally from the lower end of the reservoir that isconnected by an aperture in the reservoir base with the outlet tube,'acap having an annular projecting rim at its upper end and a dependingannular fiange adapted for screwthreaded engagement-with the upper endof the reservoir, a packing ring secured on the cap by the annular rim,an air tube opening through the cap and extending toward the lower endof the reservoir, an outer vaporizin tube concentrically secured on theair tube y means afi'ording passages between the tubes for the entirelength of the outer tube, said concentric tubes having alined aperturesin their walls, a springreturned compression cylinder telescoping overthe upper end of the reservoir, an air inlet valve in the lower head ofthe compression'cylinder, an annular shoulder on the upper end of thereservoir, an inner annular flange in the lower end of the compressioncylinder adapted to engage the reservoir shoulder, and a lug on thelower endof the reservoir adapted to pass through a slot in said flange.
